Document Summary
Recognized that organisms that had simple nervous systems (few neurons) have to accomplish the same sorts of tasks as more complex organisms but with less. We (humans) may be a little more exact and precise in our responses but they are ultimately the same as a sea slugs. At the basic level we do the same things; we need things and avoid things for survival. Our nervous system is there to get us what we need and avoid what will harm us. If we look at aplysia we see an organism with only a few hundred neurons to control everything. He recognized that there were different behaviours that can be exploited in aplysia (different types of responses that could be elicited) that could be subjected to associative learning conditions. To put very simply, aplysia don"t like to be touched and they respond to when they are touched.
